The new addition is McDreamy. "Bridget Jones's Baby" will be Dempsey's first big screen project after leaving the long-running television series "Grey's Anatomy."

Zellweger said she is happy to be playing Bridget Jones again, and to revisit London to film, E! News reported.

The third installment of the movie has long been in gestation, so the lead cast members entertained the notion that the film may not materialize.  They were in a for a surprise when Universal Pictures confirmed the final cast and the cameras began to roll.

"Bridget Jones's Diary" was released back in 2001, followed three years later by "Bridget Jones: The Edge of Reason. Zellweger made news earlier this year when fans and reporters noticed that she looked startlingly different.

The new movie has whetted the appetite of fans of the film series, especially since the storyline now focuses on a sophisticated looking heroine who, at 43, is successful, single, and pregnant.

Bridget Jones is a calorie-counting working woman obsessing over her physical appearance and love life in the first two films.

In the third film, she has advanced in age and reached her ideal weight,  but she "still hadn't solved any of her issues about love and loneliness," director Sharon Maguire said in an interview with Entertainment Weekly.

Zellweger has been vocal in expressing how glad she was to be portraying the iconic role again.
